Setting base currency for each product.

Would love to see the option to set the base currency for each product in the admin area. Reasoning below......

A store in Canada buys products from suppliers in the USA and Canada. The USA supplier says "the Minimum Advertised Price" allowed for my item is $100 USD. The supplier in Canada says the "MAP" for my product is $100 CAD. With currency fluctuations and only having one set currency for the store at the admin level, one of these products will always be off of that $100 mark.

There have been several threads on this topic in the past here.

It would be nice to see that I can set a certain product's price as $100 USD in the admin area so that even if my shop allows CAD and USD for the shopper, that product price will vary in CAD but will always be $100 USD. I hope that all makes sense.

Perhaps this is just a Canadian thing, but we are often stuck having to follow MAP rules from different countries in different currencies.

Virtuemart (extension for Joomla) has this feature and we do use Joomla for our main website, but Zen Cart just has so much more going for it overall and we want to stay with Zen Cart.
